I've been on the lookout for genuine Montessori materials that don't cost an arm and a leg and after a long and mostly fruitless search I found an awesome resource! A Plus Montessori is a discount retailer with amazing prices and everything I've been looking for.
I've been on the lookout for a pink tower and everywhere I looked they were easily $100! For wooden blocks! Making one myself was pretty much out of the question so I had almost given up on the authentic pink tower experience (nesting blocks anyone?) when I found one on A Plus Montessori for $26.95.
$26.95? That's, like, affordable.
